Fig. 3 is a plan view of the inner face of the can endwith the liner applied to the flange thereof. J

Fig. i is a central transverse section showing the can end and the liner before being assembled.

Fig. 5 is a central transverse section of the can end with the liner applied to the flange I thereof. r Inthe drawings, the reference numeral 1 designates a can end,'here shown as having a straight, or non-curled peripheral flange 2,

upon which rests, in freely movable relation, the ring liner 3. The inner bounding shoulder-.4 of the flange 2 (which is usually a straight wall) is contracted or crimped, at the point 5 to provide an'annular or circum-- -fe'-rential groove 7, as shown clearly in Figs.

4' and 5 of the drawings, so that the diameter of said Shoulder i at said point 5 is less than the diameter of said shoulder 4 at the point 6, I 4

The inner diameter of the ring liner 3 is approximatelyequal to the outer diameter 'then gradually forcing the remainder over theshoulder of the fiange until the whole of the inner edge of the said liner is seated or rests. withinth-e annular groove 'Z.- When the liner isentirelyinposition onthe flange, as shown in, Fig. 5 of the drawings, it is retained by the enlarged overhanging portion Got the shoulder 4, While being free to move upon the flange.-

1 The object of providing means-for looselyretaining the liner upon the flange'of the. can-end is thus achieved without inturning or curling'the edge of the fiange 2. I 'Having'thus described my inventiornwhat I claim as. new and desire to protect by Letters Patent is i 1. In combination, acan 'end clfor the closure of sanitary cans having an outwardly projectingflange -for the scan/ting thereof to a can bo dy,* said. flange being bounded by a peripheral recess, said structed angular seat for the can top, and

and a, llOIlQlfUillC thin fibrous ring liner having" an inner diameter than the greatest diameter of said shoulder held in said recess by the outwardly (Elitmltlil'tg' lower part of said shoulder.

A can end for the hermetic closure of: sanitary cane, the seine-being formed with a peripheral shoulder to enter Within the mouth of the can and with a flange eptending outward, from the, upper part of said shoulder, said shoulder being formed with an inward peripheral recess, and a paper ring liner having an inner dinmetei less than the atest diameter of said shoulder held loosely and freely i'imvnhle 1;1 end reeess by the outwardly extendin lower part i of said she-olden t.

A can end for the hermetic closure of Sfitllltflity cans, the same beingi med with {I peripheral shoulder to enter Within the month of the can and with a flange extend ing outward from the upper part oftziid shoulder, said shoulder being :torme'don on inward and up 21rd incline to leave a, nurrow and rounded lower edge and a.- recess above said edge, and an inelastic paper ring liner held on the inclined part of said shoulder above said edge, its internal diameter heii'ig slightly less thanthe greatest diametor of said edge.
